The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of surf on the way for Jaconé, but you’re gonna have to be patient through the first weekend – it’s a bit of a rough start.
The opening salvos on Friday the 21st are small and weak. We’ve got a tiny 2.6ft swell from the east, with a short period of 8 seconds, meaning it’s weak and gutless. The combined energy is only 109, so it’s barely a pulse. The highlight is Friday morning when it’s glassy – a light north wind at 3 mph. It’s surfable, but there’s zero power. Friday afternoon is a total write-off with a howling onshore south-west wind at 22 mph, so just forget it.
Saturday the 22nd is worse. The swell bumps up to 4.9ft by morning and 6.9ft by afternoon, but the wind is onshore from the south-southwest, making it a messy, blown-out mess. The afternoon period jumps to 11 seconds, which is decent, but the wind is ruining any chance of quality. The water here is about 72.5°, which is a touch warmer than average for this time of year – not a big deal, but noticeable when you’re suiting up.
Sunday the 23rd starts to get a little more interesting. The swell drops back to 5.6ft from the south-southwest with a 10-second period, and the wind goes cross-offshore from the east-northeast. The combined energy jumps to 587, so there’s some life in the water. The waves will be clean, but it’s still a bit messy and only marginal. Not a standout, but a paddle-out is on the cards.
Now, Monday the 24th is where it starts to get serious. The swell jumps to 7.2ft from the south with a long 13-second period, and the energy spikes to 1523 – that’s moderate wave energy, and you’ll feel it. The wind is light cross-off, so the morning should be clean, though there’s light rain around. The afternoon builds to 8.2ft with a 14-second period and a whopping 2918 energy, but the wind shifts cross-shore, which will put a bit of a chop on it. It’s getting big, so this is for the experienced crew only.
The real standout is Tuesday the 25th morning. The swell is a solid 8.2ft from the south, period of 14 seconds, and the combined energy is massive at 3029. The wind is cross-off from the east-northeast at a gentle 9 mph, keeping the surf clean. This is excellent surf for experienced surfers, and the consistency is there. The crowd factor at Jaconé is "sometimes", so expect a few locals out, but it’s not a zoo. The south swell direction is a bit off optimum for this exposed spot, which prefers a south-east angle, but with that much energy and a long period, it’s going to produce some powerful, well-shaped lines. If you’re up for a big day, this is the one.
Wednesday the 26th morning is another cracker. The swell holds at 7.9ft from the south with a very long 16-second period, and the energy is 2824. The wind is offshore from the east-northeast, so it’s offshore and clean. This is a classic groundswell setup – perfect for a point or reef, but at a beach break, that long period can make the waves stand up and barrel or just close out. It’s for experts only, and it’s going to be a proper session.
Thursday the 27th morning is still good, with a 6.2ft south swell at 14 seconds, 1554 energy, and a moderate offshore wind. It’s a step down in size, but still clean and powerful. After that, the swell begins to fade.
Friday the 28th sees the swell drop to 3.6ft with a 12-second period, but the wind is offshore and light, making for clean conditions. The energy is 768, so it’s still a fun wave. Saturday the 29th has a new pulse of 5.6ft from the east-northeast, but the period is short at 8 seconds, so it’s a bit of a windswell. The morning has gentle offshore wind, so it’s clean, but the quality is just average.
From Sunday the 30th through to the end of the run, we’ve got a long gap of small, weak, or blown-out surf. The energy drops to under 100, winds are mostly onshore, and the swell is tiny. There’s a brief window on Thursday the 3rd of September with a tiny 2.0ft swell and offshore wind, but it’s barely surfable. Saturday the 5th of September morning offers a 3.3ft south-southwest swell with a 10-second period and light offshore wind, giving you a clean, knee-high wave. It’s a last gasp, but nothing to write home about.
So, the big call for the best on offer is Tuesday the 25th morning – the combination of

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
